Paper becomes weaker and more fragile when wet due to hydrogen bond disruption
the verdict
SUPPORTED
the evidence backs this
confidence 88/100
Paper and cellulose-based materials lose strength and structural integrity when exposed to moisture due to the interaction of water with the material's hydrogen-bonding network.
